An emitter tip for a corona discharge device. The emitter tip comprises an
elongated body with a tapered end. The body defines a central passage and
the tapered end defines a tip passage in fluid communication with the
central passage. A method is provided for controlling electrostatic
charge comprising providing a voltage source; providing a pressurized
fluid source; connecting the emitter tip to the voltage source and to the
fluid source; passing the fluid through the emitter tip; and electrically
energizing the emitter tip.
